El Niño is now stronger than at any point in the last 1,000 years, study finds

A new study reconstructs a thousand-year ocean-surface temperature record from fossilized Galápagos corals and shows that the current El Niño event is the strongest observed in the past 1,000 years. Researchers note that while ENSO drives major year-to-year climate variability, the unprecedented intensity suggests added atmospheric and oceanic energy from global warming may be amplifying its swings.
